The Loong Max battery 2250 three cell 20C delivers 30 amps plus. I've also tried the  HXT 3200 20-30C and it delivers over 45 amps. I have a  Zippy 4400 15C three cell and it delivers 60 amps plus.

I have not tried to push the limits. The battery might "Puff".   The batteries were all cool to touch. I'm overly pleased with these batteries from Hobbycity.

They are very reliable so far. I'll give you more figures and reports as they are used.

Basicly, the application determines the worth of the battery and in each case these batteries meet the application. For sport flying they are fine. I would keep this forum going because we need more reports of the Thunder Power, Polyquest and other competition batteries.

My Hyperion Litestorm pack is one. Costs twice as much. I delivers it's rated discharge throughout a full hard flight. I don't have an in flight monitor, all I can do is test before and after the use, and I don't "measure" the temp of the pack...I touch measure. The Hyperion Pack is superior.

I'd like to hear from any and all about different packs, and I'd like to hear more reports on the Zippy batteries. I'm putting the Zippy in my DHC-2 Beaver from Eflite. Tests will involve a flight directly over the field, trying to determine it's behavior in a real situation, not a test run. The reciever will be powered by separate battery. (two cell and UBEC) The Test will only involve the Motor so that a recovery could be made. After I can determine that the plane is cool, I'll remove the test set up, and power the UBEC from the motor battery.

There is a certain amount of "trust" in the Zippy battery.

I have Servos from Hobbycity as well, and will post when I find out more.
